HTC HD2 delivers an experience your senses have been waiting for. The unprecedented 4.3-inch pixel-packed display is stunning. The world's first capacitive touch technology on a Windows phone along with 1 GHz processing power ensure a smooth and lightning-fast response to the lightest touch of your finger.Most importantly, it is the first Windows phone to embody HTC Sense - a holistic experience that focuses on making phones work in the most intuitive way. Customize the phone by prioritizing essential features like mail, calendar, messaging, browser and more. Next, with just a tap, put shortcuts to the most important people, favorite websites, or most used application right on the home screen. Your phone doesn't only reflect your personality; it also tunes into your location. The clock automatically updates to the local time wherever you are. You can see the outside temperature and weather at a glance. And, if you choose the weather wallpaper, you'll get a brilliantly lifelike animation that lets you virtually feel the sun's rays or the chill of the breeze without setting a foot outside.
